phenotypic expression-- genes and the environment

• • The genotype has an important role in determining the phenotype, but it can be affected by environmental influences. 
• • Therefore, an organism’s genotype and environment determine its phenotype.
• • If an individual with a given genotype develops in one environment, its phenotype may be different if it had developed in a different environment:
• • a human cannot grow to the full potential that is coded in their genotype if they are undernourished or if a bone disease affects their growth
  • a tree will be stunted in height if it does not receive the water and minerals needed to reach its genetic potential
